New renewably-sourced polyesters from limonene-derived monomers

The functionalisation of limonene has enabled the synthesis of two renewably-sourced monomers for the formation of terpene-derived polyesters. Three methods for the synthesis of the novel hydroxy-acid 6 are reported and their green-credentials scrutinised through comparison of their sustainability-metrics. Step-growth homo-polymerisation of 6 is demonstrated to yield a low molecular weight (2.6 kDa) novel polyester with 100% of its carbon content originating from the terpene starting material. The corresponding diol 2 is shown to act as a co-monomer with a renewable diacid. The resultant polyesters display impressive Mns of up to 30 kDa with Tgs between -6 and 24 °C. These materials have been shown to depolymerise under basic conditions for reclamation of the diol monomer 2.

Stoichiometric Hydroboration-Oxidation Reaction of Monocyclic Monoterpenoids: A Mechanistic Approach

The stoichiometric studies on hydroboration-oxidation reactions of (-)-carvone have been carried out to gain an insight into the mechanism of formation of unusual products 2-oxo-p-menth-9-ols (IVb,c), p-menth-2,9-diols (Xa,b) and p-menth-1-en-9-ol (VII).Based on high resolution PMR spectral data, the stereochemistry of IVb,c and Xa,b has been deduced.Similiar studies have been extended to (+)-dihydrocarvone and (-)-carveol.
